DEVICE FOR LIFTING 'THE FRAMES OF RAILROAD-TRUCKS- SPECIFICATION i rming p r f L r P n Aha- 752507, dated April 19, 1904. v

Application filed October 27, 1903.

To all whom it may concern;

Be it known that 1, WILLIAM Sonorr, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented new and useful Improvements in Devices for Lifting the Frames of Railroad- Trucks, of which the following is a specification.

This invention relates to improvements in an apparatus for lifting the frames of railroad-trucks without removing the wheels from the tracks.

Heretofore when the brasses of bearings became hot or worn and had to be removed while the train was on the road it required considerable time and labor to make the necessary repairs.

It is therefore the purposeof my invention to overcome the objectional delays and cumbersome operations incident thereto and provide an apparatus which can be quickly and conveniently handled, that the brass may be removed with comparatively little delay.

A further object of the invention is to provide an apparatus for elevating the truckframe without lifting the wheels from the tracks, which is operated by the movement of the engine or car, as the case may be, and therefore dispense with the use of manuallyoperated mechanism for this purpose.

In the drawings, Figure 1 is avertical central section of a truck and my invention applied and ready to be operated. Fig. 2 is a detail view of the same, but showing the truckframe elevated. Fig. 3 is a transverse section on the line 3 3, Fig." 2. Fig. 1 is a similar view, but illustrating the position of the lifter before the truck is moved and disclosing a slight modification. Fig. 5 is a perspective view of the preferred form of my invention. Fig. 6 is a vertical section of the same. Fig. 7 is a transverse section on the line? 7 of Fig. 6. Fig. 8 is a detail perspective view of the modification of the lifting-block shown in Fig. 1 and illustrating a filler-block which coacts therewith,

The same numerals refer to like parts in all the figures.

1 represents a railroad-track, and 2 the ties supporting the same. A truck 3 is mounted Serial No. 178,706. (No model.)

"on the tracks, and asit is essential to a comprehensive understanding of my invention that the movements of the truck be understood a general statement of the parts'will be given; The wheels 4 are carried on an axle 5, mounted in bearings 6, comprising the usual collar 7, brass 8,'and box 9. The box is mounted to slide on the frame 10, composed of the upper stringer 11 and the tie-rod 12. Parallel bars 13 connect the adjacent boxes 10, and a spring 14 is placed between the stringer 11 and hangers between said bars 13.

I have described only one side of the truck; but as the structure is so well known it is to be understood that both sides are identical.

16 represents a base-block which 7 is inclined on its upper surface 17 and is provided with ways 18. Depending from the under side of the block are pins or the like 19, which are embedded in the ties2 when theinvention is being operated. A lifting-block 20 is provided on its lower side with an inclined sur face 21 and adjacent ribs formings ways 22, which work in the ways 18 of block 16, the upper surface of said lifting-block being flat ribs 22 the under side of the lifting-block is and on a horizontal-plane. Intermediate the provided with a series of grooves'-23, into which fit and freely roll on' the surface 17 antifriction-rollers 24:2" The lifting-block is limited in its movement up the inclined surface 17 by astop 25, and its movement in the opposite direction is checked by a pin or bar 36. In Figs. 4 and 8 I have shown two slight modifications to adapt the invention to certain kinds of trucks and conditions likely to come about. The lifting-block is centrally grooved at 20 to'form two upstanding flanges 27 27, which straddle the tie-rod 12 and bear directly on the bottom of the box 9. Should the bottom of the truck-frame-be a little high from the ties and it is desired to lift the frame and not the box, a filler-piece 29 may be dropped in the groove 20 of the liftingblock. Piece 29 has end flanges 30 30, which look it to the lifting-block when it is dropped in place. a

In operation the apparatus is seated on the cross-ties 2, the liftingblock being at the lowest level, with its upper flat surface under ter has been found preferable.

the tie-rod 12 at a point below the journal to be elevated for the removal of its brass, as shown in Fig. 1. The box-fastening devices 31 are removed and the collar 7 is withdrawn, and in order that the space between the bottom of the box 9 and the flange 32 of the collar may be filled up, that the lifting action may be applied directly to the box, I insert a filler 33, as shown in Fig. 2. The apparatus having been positioned as shown in Fig. 1, the truck is moved in the direction of the arrow a. The nuts of the frame bearing against the edge of the lifting-block start it up the inclined surface of the base-block, and as soon as it has moved far enough to take the weight of the truck it moves with the same. As the truck and the lifting-block are moved toward the highest part of the base-block the side frame of the truck and the box carried thereby are lifted from the axle, allowing the brass 8 to drop, that it may be withdrawn, as shown in Fig. 2. The brass having been removed and another inserted in its place, the movement of the truck is reversed, which causes the lifting-block to slide down the inclined surface. Hence the frame will assume its normal position on the axle. The apparatus is also removed, the filler 33 taken out, and the collar inserted and locked in the box, and the operation of changing the brass is complete.

The operation is extremely simple and does away with the usual manual appliances for lifting trucks and positively insures the truckframe being lifted from the axle and leaving the wheels on the tracks.

The compactness and durability of the invention, combined with its simplicity, enables me to produce a lifting apparatus for the purpose specified of the highest commercial type.

My inventionalso contemplates a structure for operating directly on a journal-box to elevate it against the tension of the spring 1 and away from the axle. This modification is shown in Figs. 4 and 8. The groove 20 is so proportioned that it permits the liftingblock to move without engaging the tie-rod 12. However, the flanges 20 straddle said bar and bear directly against the bottom of the box. (See Fig. t.) Such a construction obviates the necessity of lifting the weight of the truck-frame notwithstanding the lat- The modified construction may also be utilized in connection with a filler-block (see Fig. 8) for use when a truck-frame is slightly higher from the tracks than one of ordinary construction.

I For instance, if a tie-rod 12 of a standard truck is a predetermined distance from the ties and a truck of slightly-different proportions had to be operated upon and the distance between its tie-rod and the ties was an inch or two greater than the standard the filler-block would be dropped into the groove .20 to form an inclined surface on a level with the top of the flanges. This arrangement fills up the space between the bottom of a truck of unusual proportions and a standard lifting apparatus and'enables me tolift it.

Having thus described my invention, what .I claim.is

1. An apparatus for lifting a truck from its axle, comprising a base-block having an inclined surface with ways adjacent thereto, and a lifting-block having an inclined surface corresponding to the surface of the base-block, ways adjacent to said inclined surface which coact with the ways of the base-block, said lifting-block being forced up the incline of the base-block for separating the truck from the axle thereof when said truck is moved, substantially as described.
